Evaluation of different integrated pest management modules against Thrips parvispinus Karny in chilli

Abstract

The present investigation was carried out to evaluate effectiveness of different integrated management strategies against Thrips parvispinus Karny. The experiment was conducted at, Horticultural Research Station, Dr. Y.S.R Horticultural University, Lam, Guntur during the year, 2021-22 with three replications in Randomized Block Design. Total seven modules including control were evaluated for management of Thrips parvispinus. Results revealed that Module-IV was most effective. Higher chilli yield of 32.22 q/ha with 87.08 % increase over untreated control was observed in M-IV (Mulch + blue sticky traps along with need based application of insecticides viz., fipronil 80WG @ 0.2 g/L, spinetoram 11.7SC @ 1 ml/L, spirotetramat 240SC @ 0.8ml/L, acetamapride 20%SP @ 0.2g/L, thiomethaxam
25%WG @ 0.2g/L, dimethoate 30%EC @ 2ml/L sprayed sequentially at 10 days interval) followed by Module-I and Module-III and they were at par with each other with recorded yield of 30.55 q/ha and 27.77 q/ha respectively with 86.37% and 85.01% increase over control.
